Hi Kristjan,
You are correct that the statistics filters do not weight values by
cell area. It's torturous, but it might be possible to use the "Mesh
Quality" filter to compute the cell areas/volumes, a calculator filter
to compute the product of the area and a cell variable, and then run
descriptive statistics on the resulting field. But being able to
perform area/volume-weighted statistics (at least for cell data)
sounds like a good use case to support. Would you be willing to file a
feature request at http://paraview.org/Bug/ and attach your example to
it?
Thanks,
David

Hi,
I'm having difficulty using the Descriptive Statistics filter with
data
specified on unstructured grids.
The two files attached to this email demonstrate the problem. The mean
of y obtained with 2_cell_square.vtu is 0.5 whereas with
5_cell_square.vtu the mean is 0.417.
I think this happens because the mean is calculated over all the
points
without taking into account the cell area. Can anyone explain what
steps
I should follow to obtain a mean of 0.5 with 5_cell_square.vtu?
Thanks,
Kristjan
